Of course, 18-year-olds are adults in a legal sense. But they are still very inexperienced in life, heck they are not even allowed to buy beer in the US.
I'm not saying 18-year-olds shouldn't be entrepreneurs. But what Sam Altman is suggesting is just very dystopian to me, because he suggests it as an alternative to a traditional education. In his narrow view, the goal of education is only to produce people who maximize financial value.
> Everybody who wants to should be encouraged to enjoy their lives, travel, and learn
Yes. But as you probably know from your own life (if you're older than 30), this gets harder and harder. So we should especially encourage younger folks, who are still more opend-minded and have less responsibilities, to do that.
